Next, illustrating the manufacturing method of transmission mechanism 1 referring to Fig. 3.Manufacturing method in 1st embodiment is can to make
Herringbone bear is passively located in the manufacturing method of the position of engagement appropriate with gel-type resin 50.In addition, in not special area
In the case where not each 41~bearing of bearing 46, it is abbreviated as bearing and is illustrated.
As shown in figure 3, firstly, gel-type resin 50 to be coated to the back side (step S1) of bearing.In the coating of step S1
In process, the gel-type resin 50 of liquid before curing is coated to the back side of the bearing before assembling.For example, in outer ring back face
Gel-type resin 50 before circumferential whole region coating curing annular in shape.
Then, the bearing for being coated with gel-type resin 50 before curing is loaded on the state group that can be moved axially relatively
Shell 4 (step S2).The assembling procedure of step S2 includes following process, that is, by the outer ring of bearing with can be relative to shell 4 along axis
The process for being set to shell 4 to mobile state, and the process for keeping the inner ring of bearing chimeric with rotary shaft.In this case, interior
Circle becomes the chimerism that can integrally move with rotary shaft along axial direction.After implementing step S2, bearing energy and rotary shaft
It integrally moves, and can be moved axially relatively relative to shell 4 along axial direction.
After the assembling procedure of step S2, carry out herringbone bear looks for position to operate (step S3).Position operating is looked for refer to
Rotate each rotary shaft in the state of so that herringbone bear is engaged with each other, to make to act on core (to center movement) hair in engaging section
The process for waving effect.The effect being axially moveable using herringbone bear because this is acted on core, can be by the position quilt of herringbone bear
It is positioned at the position of engagement appropriate dynamicly.The position of engagement appropriate refers to as two-sided touching and reaches thrust in axial sides
The axial position of the state of balance.
In the case where carrying out the positioning of the 1st gear pair 2 in the process of step S3, make the 1st herringbone bear 11 and the 2nd
Herringbone bear 21 rotates the 1st axis 10 and the 2nd axis 20 in the state of engaging.In the 1st gear pair 2, the 1st herringbone bear 11
Left and right teeth portion and the left and right teeth portion of the 2nd herringbone bear 21 are sometimes because (engagement misses the error percentage of the engaging sections such as when rotating beginning
Difference) and become single side and touch.As an example, left teeth portion be in contact with each other but right teeth portion each other not in contact in the case where, in the 1st tooth
The engaging section of wheel set 2 generates the thrust that left side acts in the axial direction.In the 1st herringbone bear 11 or the 2nd herringbone bear 21 because of the axial direction
The thrust in left side and when left side is mobile in the axial direction, make not in contact with right teeth portion be in contact with each other and become acting on core for two-sided touching
It plays a role.In the state of the two-sided touching, left teeth portion is in contact with each other the thrust in the axial left side generated, with right teeth portion
The thrust for being in contact with each other the axial right side generated is cancelled out each other.Therefore, opposite in the axial direction in the engaging section of the 1st gear pair 2
The thrust-balancing of side effect.In the equilibrium situation, the 1st herringbone bear 11 and the 2nd herringbone bear 21 do not generate axial movement.
That is, make the engaging section of the 1st gear pair 2 to core after in the state of, the 1st axis 10 and the 2nd axis 20 are not axially moveable.
So, the gel-type resin in the process of step S3, at the back side of the bearing 41,42 coated on 10 side of the 1st axis
In the state that 50 is uncured, and the uncured shape of gel-type resin 50 at the back side of the bearing 43,44 coated on 20 side of the 2nd axis
Under state, rotate the 1st axis 10 and the 2nd axis 20.As long as then each axis 10,20 can be along axis before the solidification of gel-type resin 50
It plays a role in the engaging section of the 1st herringbone bear 11 and the 2nd herringbone bear 21 to core effect to movement, is pushed away so can utilize
Power (to center movement) changes the axial position of herringbone bear appropriately.After implementing step S3, solidify in gel-type resin 50
It is preceding no longer occur each herringbone bear 11,21 to center movement in the case where, become two-sided touching and become engagement shape appropriate
State.
Then, make that position operating is looked for continue to solidify (step S4) until gel-type resin 50.In the process of step S4,
The rotation lasts of the 1st axis 10 and the 2nd axis 20 are made solidify until gel-type resin 50.Process by implementing step S4,
The axial position of fixed herringbone bear and the axial position of bearing, complete the assembling of herringbone bear.
In this way, in manufacturing method shown in Fig. 3, high using transmission efficiency and do not allow the axial displacement of rotary shaft
In the case where bearing, it can be fixed afterwards in position by the axial position determination of herringbone bear.Thereby, it is possible to inhibit
In the fixed herringbone bear of axial position for becoming single side touching.In addition, in the transmission mechanism 1 of three axis construction, with the 2nd gear pair
The bearing 43,44 of 3 corresponding 2nd axis, 20 sides and the bearing 45,46 of 30 side of the 3rd axis also implement above-mentioned step S1~step S4
Process.In addition, the process of the process of step S3 and step S4 can be regarded as one in above-mentioned manufacturing process shown in Fig. 3
Process, such as positioning process (step S3~step S4).Positioning process is the axial position for determining herringbone bear and bearing
Process.
As described above, using the manufacturing method of the 1st embodiment, it can be relative to error percentage (meshing error) passively
Determine the position of engagement of each herringbone bear.Even if supporting the bearing of herringbone bear as a result, using (the limitation rotation of efficient bearing
The rolling bearing that axis is axially moveable), it is also easy to determine the axial position of herringbone bear and absorbs the error of gear becoming
The simplification of manufacturing process is realized in the position of the state of ingredient.Furthermore it is possible to improve efficiency, and vibration can be reduced and made an uproar
Sound.
In addition, in the 1st embodiment, due to determining axial position using gel-type resin 50, so comparing previous structure
Make reduction and lightness that such construction for clipping gasket is able to achieve part number of packages.
In addition, can be fitted in the range of not departing from the purpose of the present invention the present invention is not limited to the 1st above-mentioned embodiment
Preferably change.For example, transmission mechanism 1 is not limited to the 3rd axis 30 being set as differential carrier and the 2nd gear pair 3 is set as main
The structure of speed reducing gear pair.In the case where transmission mechanism 1 is equipped on vehicle, can also apply to for motor to be set as traveling use
The electric vehicle of power source.In such a case it is possible to the 1st axis 10 is set as the input shaft rotated integrally with the armature spindle of motor,
2nd axis 20 is set as countershaft, the 3rd axis 30 is set as output shaft.In addition, in the transmission mechanism 1 of three axis construction, all bearings
